Canola Seeding Depth and Row Spacing. 1  Canola seeds are small, and careful placement at a relatively shallow depth is required. 2  Best germination and emergence occur at 1/2 to 1 inch under conditions of good soil moisture.  Canola has difficulty emerging from crusted soil.
Serotonin plays a role in many brain processes, including body temperature regulation, sleep, mood, appetite, and pain. Problems with the serotonin pathway are linked to obsessive-compulsive disorder, anxiety disorders, and depression.he Dopamine Pathways. Dopamine is the neurotransmitter used by the reward pathway (also called the mesolimbic pathway, which is closely linked with the mesocortical pathway).
The mesolimbic pathway can be seen here as the blue projections from the VTA to the Nucleus Accumbens.The mesolimbic pathway, sometimes referred to as the reward pathway, is a dopaminergic pathway in the brain. The pathway begins in the ventral tegmental area of the midbrain and connects to the nucleus accumbens.entral tegmental area. The ventral tegmental area (VTA) is a part of the midbrain. It consists of dopaminergic, GABAergic, and glutamatergic neurons. The VTA communicates with the nucleus accumbens via the medial forebrain bundle.
